14. The measures of two complementary angles are 12x-9 and 8x+14. Find the
measures of the angles.
Step-by-step explanation:
Since they are complementry angles :
(12x-9) + (8x + 14) = 90°
20x + 5 = 90°
X = 4.25 °
Angles are 42° and 48°.
can someone help solve this math problem with steps and detail pls :) I really confused
Division first:
-2/5 / 8/15
When dividing two fractions flip
The second one over and multiply:
-2/5 x 15/8 = (-2x15)/(5x8) = -30/40 = -3/4
Now you have:
2-3/4-3/4
2-3/4 = 1 1/4
1 1/4 - 3/4 = 1/2
The answer is 1/2
Help me on this please

Consider the function g(x) = -3x - 4 if the domain value is selected from the set {-8, -2, 0, 3}, which of the following is a corresponding range value?
A. 18
B. -10
C. -13
D. -5
Answer:
C. -13
Step-by-step explanation:
Solve for g(x) by replacing x with each domain value in the set. Solving for g(x) will give you these numbers:
{20, 2, -4, -13}
-13 is the only value that appears in the range set and in the multiple choice solutions. Therefore, the answer is C. -13
C. [tex]-13[/tex] is a corresponding range value.
The domain of a function refers to the set of all values for which the function is defined.
The range is the set of all values that function takes for the given values of domain.
Domain is [tex]\boldsymbol{\left \{ -8,-2,0,3 \right \}}[/tex]
[tex]g(x)=-3x-4[/tex]
[tex]g(-8)=-3(-8)-4[/tex]
[tex]=20[/tex]
[tex]g(-2)=-3(-2)-4[/tex]
[tex]=2[/tex]
[tex]g(0)=-3(0)-4[/tex]
[tex]=-4[/tex]
[tex]g(3)=-3(3)-4[/tex]
[tex]=-13[/tex]
Range is [tex]\boldsymbol{\left \{ 20,2,-4,-13 \right \}}[/tex]
So, [tex]\boldsymbol{-13}[/tex] is a corresponding range value.

Answer:
For question 2 the slope is 1. So what you do is get the points you need to put on the graph and move them up one. Like how you did on question 1.
(0.5, 5) (1, 10) (1.5, 15) (2, 20) (2.5, 25)
Question 3 is the same thing but the slope is now 2. Then you would have to pin the points as...
(1, 2) (2, 4) (3, 6) (4, 8) (5, 10)

Solve the equation 4+x/-9=6
Answer:
x = -18
Step-by-step explanation:
4+ x / -9 = 6
x / -9 = 6 - 4
x / -9 = 2
x = 2*-9
x = -18
found this deimos Google hope this helps -
x in (-oo:+oo)
x/4-9 = 6 // - 6
x/4-9-6 = 0
1/4*x-15 = 0 // + 15
1/4*x = 15 // : 1/4
x = 15/1/4
x = 60
A repair bill for your car is $553. The parts cost $265. The labor cost is $48 per hour. Write and solve equation to find the number of hours T of labor spent repairing the car
Equation : __ =553
T= ___ hours
Answer:
6
Step-by-step explanation
265+48=313
553-313=240
240/60=6
Answer:
equation : 265 + 48T = 553
T = 6 hours
Step-by-step explanation:
equation
553 - 265 = 288
288 /48 = 6
the number of hours spent is 6
equation : 265 + 48T = 553
T = 6 hours
